Description

【０００１】
【発明の属する技術分野】
この発明は、内視鏡管路のブラッシング洗滌を自動で行う内視鏡洗滌ブラシ及び内視鏡洗滌装置に関する。
【０００２】
【従来の技術】
内視鏡内に設けられた長い管路内を洗滌する内視鏡洗滌ブラシ及び管路内に洗滌ブラシを挿入して洗滌する内視鏡洗滌装置が知られている（例えば、特許文献１〜４参照。）。
【０００３】
特許文献１は、内視鏡管路内に挿入される柄部の先端部にブラシ部を設けるとともに、このブラシ部の先端側に可撓性を有する弾性部材を介して球状部材を設けたものである。このブラシ部は２本のステンレス線材の間にナイロン繊維等からなるブラシ毛を挟み込んで植設したものである。
【０００４】
特許文献２は、内視鏡管路内に挿入される柄部の先端部に関節部を介してブラシ部を設け、ブラシ部が関節部から任意の方向に回動するようにしたものである。
【０００５】
特許文献３及び４は、内視鏡を収納する洗滌槽内に内視鏡管路に挿入されるワイヤの先端部にブラシを設けるとともに、ワイヤを進退させる駆動機構として一対のローラーによってワイヤを挟持搬送するようにしたものである。
【０００６】
すなわち、内視鏡管路をブラッシングできるように洗滌ブラシを挿入／抜去できるユニットが設置されている。このユニットにはモーターの駆動で回転する一対のローラーが設けられている。そして、洗滌ブラシのワイヤを一対のローラーで挟み込むような形でローラーを回転させることで、洗滌ブラシの内視鏡管路内への挿入／抜去を行っている。

【発明が解決しようとする課題】
しかしながら、内視鏡管路は、管路径が異なる複数の管路がコネクターを介して接続されている。そのため、これらコネクター近辺には段差がある。このような段差のある長い管路を洗滌ブラシが挿入／抜去される。従って、この段差に洗滌ブラシの先端部が衝突すると、ステンレス線材が変形したり、引っ掛かって洗滌ブラシをスムーズに移動できなくなることがある。
【００１２】
また、内視鏡洗滌装置は、装置内に設置されているブラシ収納管路に収納された洗滌ブラシを進退駆動する駆動手段である一対のローラーによって挟み込み、このローラーを回転させることで洗滌ブラシを進退させている。一般に洗滌ブラシの挿入部は密巻コイル状のステンレスワイヤーで形成されており、ローラーはゴム部材で形成されている。従って、洗滌ブラシを進退させるためにローラーを回転させると洗滌ブラシの挿入部とローラーのゴム部が擦れ合うので、その摩擦によりローラーが削れてしまう。これにより、洗滌ブラシの進退時にローラーの空回りしたり、ローラーの削れ粕が洗滌中の内視鏡管路に入り込む虞がある。
【００１３】
この発明は、前記事情に着目してなされたもので、その目的とするところは、内視鏡管路をスムーズに進退して洗滌でき、しかも耐久性のある内視鏡洗滌ブラシ及び内視鏡洗滌装置を提供することにある。
【００１４】
【課題を解決するための手段】
この発明は、前記目的を達成するために、請求項１は、内視鏡管路に挿入される長尺の挿入部と、前記挿入部の先端部に設けられ、硬質な線状の材料からなる複数の線状部材に前記内視鏡管路の洗滌を行うブラシ毛を撚り込んで形成したブラシ部材と、前記ブラシ部材より前記先端部の先端側に設けられた弾性を有する材料からなる弾性部材と、前記ブラシ部材を前記内視鏡管路に案内するために球状に形成された前記挿入部の先端に設けられた球状部材とを具備したことを特徴とする内視鏡洗滌ブラシにある。
【００１５】
請求項２は、請求項１の前記挿入部を弾性を有する樹脂製の材料から形成したことを特徴とする。
【００１６】
請求項３は、管路を有する内視鏡を収容して洗滌可能に構成した洗滌槽と、前記洗滌槽に収容された前記内視鏡が有する前記管路に挿通されて前記管路の内面の汚れを除去する長尺の挿入部を有する洗滌ブラシと、前記洗滌ブラシの先端部に設けられ、硬質の線状の材料からなる複数の線状部材に前記内視鏡管路の洗滌を行うブラシ毛を撚り込んで形成したブラシ部材と、前記ブラシ部材より前記先端部の先端側に設けられた弾性を有する材料からなる弾性部材と、前記ブラシ部材を前記管路に案内するために球状に形成された前記挿入部の先端に設けられた球状部材と、前記洗滌ブラシの挿入部を挟持して互いに逆方向に回転することで前記洗滌ブラシを前記管路内へ送り出すように構成された一対のローラーを有する送り出し手段とを具備したことを特徴とする内視鏡洗滌装置にある。
【００１７】
請求項４は、請求項３の前記洗滌ブラシの前記挿入部を弾性を有する樹脂製の材料から形成したことを特徴とする。
【００１８】
前記構成によれば、洗滌ブラシのブラシ部材の先端側に弾性部材を設け、更にその先端側にガイドとなる球状部材を設けることにより、洗滌ブラシを装置内管路から内視鏡管路の間を進退させるときに、管路内径に段差が存在し、洗滌ブラシの先端部が衝突しても、先端部が弾性部材で形成されているため、この部分が反発し、段差への引っ掛かりを防止できる。そのため、洗滌ブラシが管路内をスムーズに進退移動でき、摩耗、損傷が軽減される。
【００１９】
【発明の実施の形態】
以下、この発明の各実施の形態を図面に基づいて説明する。
【００２０】
図１〜図３は第１の実施形態を示し、図１は洗滌ブラシの側面図、図２は内視鏡洗滌装置の概略的構成図、図３（ａ）（ｂ）は図２のＡ部を拡大した断面図である。
【００２１】
図１に示すように、洗滌ブラシ１の挿入部２は、例えば細長いステンレスワイヤーをコイル状に巻回した密巻コイル２ａによって形成されている。挿入部２の先端側は細長いステンレスワイヤーをコイル状に巻回した疎巻コイル２ｂによって形成されている。
【００２２】
挿入部２の疎巻コイル２ｂには複数本の硬質ステンレス線材等の線状部材３を撚合し、両線状部材３の間に束状のブラシ毛を撚り込んで形成したブラシ部材４が設けられている。さらに、ブラシ部材４より先端側には細長いステンレスワイヤーをコイル状に巻回した弾性部材としての疎巻コイル２ｃが設けられ、この疎巻コイル２ｃの先端部にはステンレス等の球状部材５が設けられている。そして、線状部材３の両端部は疎巻コイル２ｂ，２ｃに半田付けされ、球状部材５の首部５ａは疎巻コイル２ｃに挿入された状態で半田付けされている。
【００２３】
従って、挿入部２は、湾曲されても真直ぐに復元するように弾性を持っている。また、ブラシ部材４より先端側の疎巻コイル２ｃは、特に優れた弾発力を有しており、軸方向に大きな押圧力が加わっても座屈しないように形成されている。
【００２４】
次に、内視鏡洗滌装置について説明すると、図２に示すように構成されている。すなわち、洗滌しようとする内視鏡１０を収容する洗滌槽１１が設けられている。洗滌槽１１には水道蛇口（図示しない）から洗滌液がフィルター（図示しない）を介して注入されるようになっている。
【００２５】
洗滌槽１１の側壁の一部には洗滌液吸引口１２が設けられ、この洗滌液吸引口１２は洗滌液供給源としての洗滌液ポンプ１３を有する装置内管路１４に接続されている。装置内管路１４は、前記洗滌ブラシ１を進退自在に収納するブラシ収納管路１５に接続され、このブラシ収納管路１５は洗滌槽１１の側壁の一部に設けられた洗滌液入口１６に接続されている。
【００２６】
ブラシ収納管路１５の途中にはローラー収納部１７が設けられている。ブラシ収納管路１５は洗滌ブラシ１の全長が収納できる長さを有しており、装置内部にコンパクトに収納できるように丸められている。また丸め過ぎると洗滌ブラシ１の挿入／抜去時の抵抗となるため、ある一定以上のＲを確保している。また、ブラシ収納管路１５の除水性を考慮し、ブラシ収納管路１５の内径は洗滌ブラシ１の外径より若干大きめ程度の管路径となっている。
【００２７】
ローラー収納部１７は、ケーシング１８内に洗滌ブラシ１の挿入部２を挟持しながら搬送する送り出し手段として、モーター（図示しない）によって正逆回転可能な一対のローラー１９が設けられている。ケーシング１８の水平方向には一対のローラー１９の接合点に対向して洗滌ブラシ１の出入口２０ａ，２０ｂが設けられている。
【００２８】
洗滌液入口１６は洗滌チューブ２１を介して内視鏡管路２２に接続されている。内視鏡管路２２を洗滌ブラシ１でブラッシングするのは基本的に吸引管路２３であり、この吸引管路２３は、シリンダ部吸引管路開口部２３ａを中心に挿入部側管路２３ｂとライトガイド側管路２３ｃに分岐している。挿入部側管路２３ｂの途中には内視鏡１０の症例に使用する図示しない正検鉗子や把持鉗子等の処置具類を挿入／抜去する鉗子口管路２３ｄが形成されている。
【００２９】
次に、前述のように構成された内視鏡洗滌装置の作用について説明する。まず、内視鏡洗滌装置の電源を投入し、洗滌槽１１に内視鏡１０をセットし、洗滌ブラシセットボタンを押すと、制御部からの信号によってローラー収納部１７のモーターが駆動し、一対のローラー１９が回転する。そこで、洗滌液入口１６からユーザーが洗滌ブラシ１の挿入部２の末端側をブラシ収納管路１５に挿入する。洗滌ブラシ１の挿入部２の末端側が回転している一対のローラー１９に到達して挟持されると、洗滌ブラシ１はブラシ収納管路１５に引き込まれる。
【００３０】
次に、洗滌スタートボタンを押すと、洗滌工程を開始する。水道蛇口からフィルターを介して洗滌液が洗滌槽１１に供給される。洗滌槽１１に一定量注入された後、ポンプ１３が作動し、ブラシ収納管路１５から洗滌チューブ２１を介して内視鏡管路２２に洗滌液を注入しながら流液洗滌を行う。このとき、一対のローラー１９は洗滌ブラシ１の挿入部２をブラシ収納管路１５に引き込む方向と逆方向に回転し、洗滌ブラシ１が内視鏡管路２２に挿入される。
【００３１】
内視鏡管路２２に洗滌ブラシ１を挿入した後、一対のローラー１９は洗滌ブラシ１の挿入部２を挟持しながら送り出す方向と引き込む方向を繰り返すことにより、洗滌ブラシ１が内視鏡管路２２内を進退移動し、内視鏡管路２２をブラッシングしながら流液洗滌する。
【００３２】
このとき、洗滌ブラシ１のブラシ部材４が内視鏡１０の挿入部先端開口１０ａから突出したら、それを検知してモーターを逆転させて洗滌ブラシ１を引き込み、所定量だけ引き込んだら再び送り出すようにモーターを制御してもよく、内視鏡１０の機種によって内視鏡管路２２の長さが異なることから内視鏡１０の識別情報を入力してモーターが自動的に正転と逆転を繰り返すように制御してもよい。
【００３３】
また、洗滌ブラシ１の進退移動範囲である内視鏡管路２２の管路内径及び洗滌チューブ２１と内視鏡管路２２との接続部２４における管路内径は異なる。このため、図３（ａ）（ｂ）に示すように、接続部２４に段差２５がある。従って、洗滌ブラシ１を内視鏡管路２２に挿入する際に、洗滌ブラシ１の先端部が段差２５に衝突するが、この発明の洗滌ブラシ１のブラシ部材４の先端側には弾性を有する疎巻コイル２ｃを介して球状部材５が設けられている。
【００３４】
従って、球状部材５が段差２５に衝突しても、挿入部２にさらに押し込み方向ａの力が加わると、弾性を有する疎巻コイル２ｃが反発して球状部材５が矢印方向ｂに移動し、ブラシ部材４が段差２５をスムーズに乗り越えて進むため、ブラシ部材４が損傷することはない。つまり、洗滌ブラシ１の進退移動範囲である内視鏡管路２２の管路内径に段差があってもブラシ部材４が引っ掛かることはなく、スムーズに進退することからブラシ部材４の摩耗を低減でき、洗滌ブラシ１の耐久性を向上できる。
【００３５】
図４は第２の実施形態を示し、洗滌ブラシ１の挿入部２６は弾性を有するパイプ状の樹脂材料によって形成されている。本実施形態によれば、洗滌ブラシ１を進退させる一対のローラー１９がゴム材によって形成されているが、ローラー１９に接触する部分が樹脂材料であるため、ローラー１９の摩耗を低減でき、摩耗によって削れ粕等が発生することによる不具合を解消できる。
【００３６】
なお、本実施形態においては、洗滌ブラシ１の挿入部２６は弾性を有するパイプ状の樹脂材料によって形成したが、第１の実施形態に示す密巻コイル２ａの外周面を樹脂材料によって被覆してもよい。
【００３７】
前記各実施形態によれば、次のような構成が得られる。
【００３８】
（付記１）内視鏡管路を洗滌する洗滌ブラシにおいて、長尺の挿入部の先端部に硬質線材によってブラシ毛を撚り込んでブラシ部材を設け、このブラシ部材の更に先端側に弾性部材を装着し、更にその先端側にガイドとなる球体を取り付けたことを特徴とする内視鏡管路洗滌ブラシ。
【００３９】
（付記２）内視鏡管路を洗滌する洗滌ブラシにおいて、挿入部を細長い弾性体の樹脂材料で形成したことを特徴とする内視鏡管路洗滌ブラシ。
【００４０】
なお、この発明は、前記実施形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、前記実施形態に開示されている複数の構成要素の適宜な組合せにより種々の発明を形成できる。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。さらに、異なる実施形態に亘る構成要素を適宜組合わせてもよい。
【００４１】
【発明の効果】
以上説明したように、この発明によれば、内視鏡管路をスムーズに進退して管路を洗滌できる内視鏡洗滌ブラシを提供できる。また、内視鏡洗滌装置及び内視鏡管路に段差があっても、スムーズに乗り越えて進退するため、洗滌ブラシの摩耗、損傷を低減でき、洗滌ブラシ及び内視鏡洗滌装置の耐久性を向上できるという効果がある。

In the middle of the insertion portion side channel 23b, a forceps port channel 23d for inserting / removing treatment tools such as a positive forceps and a grasping forceps (not shown) used for the case of the endoscope 10 is formed.
[0029]
Next, the operation of the endoscope cleaning device configured as described above will be described. First, when the power of the endoscope cleaning device is turned on, the endoscope 10 is set in the cleaning tank 11 and the cleaning brush set button is pressed, the motor of the roller storage unit 17 is driven by a signal from the control unit, and Roller 19 rotates. Then, the user inserts the distal end of the insertion portion 2 of the cleaning brush 1 into the brush storage channel 15 from the cleaning liquid inlet 16. When the distal end of the insertion portion 2 of the cleaning brush 1 reaches and is pinched by the pair of rotating rollers 19, the cleaning brush 1 is drawn into the brush storage channel 15.
[0030]
Next, when the washing start button is pressed, the washing process is started. The cleaning liquid is supplied to the cleaning tank 11 from a water tap through a filter. After a certain amount is injected into the cleaning tank 11, the pump 13 is operated, and the cleaning liquid is washed while the cleaning liquid is injected from the brush storage pipe 15 to the endoscope pipe 22 via the cleaning tube 21. At this time, the pair of rollers 19 rotates in the direction opposite to the direction in which the insertion portion 2 of the cleaning brush 1 is drawn into the brush storage channel 15, and the cleaning brush 1 is inserted into the endoscope channel 22.
[0031]
After the cleaning brush 1 is inserted into the endoscope channel 22, the pair of rollers 19 repeats the direction in which the cleaning brush 1 is fed out and the direction in which the cleaning brush 1 is inserted while nipping the insertion portion 2, so that the cleaning brush 1 is moved in the endoscope channel. The endoscope tube 22 is moved forward and backward to wash the flowing liquid while brushing the endoscope channel 22.
[0032]
At this time, when the brush member 4 of the cleaning brush 1 protrudes from the opening 10a of the insertion portion of the endoscope 10, it is detected, the motor is reversed, and the cleaning brush 1 is pulled in. The motor may be controlled, and since the length of the endoscope conduit 22 differs depending on the model of the endoscope 10, the identification information of the endoscope 10 is input and the motor automatically repeats normal rotation and reverse rotation. May be controlled as follows.
[0033]
Further, the inside diameter of the endoscope duct 22 which is the range of movement of the cleaning brush 1 and the inside diameter of the duct at the connection portion 24 between the washing tube 21 and the endoscope duct 22 are different. For this reason, as shown in FIGS. 3A and 3B, there is a step 25 in the connecting portion 24. Therefore, when the cleaning brush 1 is inserted into the endoscope channel 22, the distal end of the cleaning brush 1 collides with the step 25, but the distal end side of the brush member 4 of the cleaning brush 1 of the present invention has elasticity. The spherical member 5 is provided via the loosely wound coil 2c.
[0034]
Therefore, even if the spherical member 5 collides with the step 25, if a force in the pushing direction a is further applied to the insertion portion 2, the sparsely wound coil 2c having elasticity repels and the spherical member 5 moves in the arrow direction b, Since the brush member 4 smoothly passes over the step 25, the brush member 4 is not damaged. In other words, even if there is a step in the inner diameter of the endoscope conduit 22, which is the range of movement of the cleaning brush 1, the brush member 4 does not get caught and moves smoothly, so that the abrasion of the brush member 4 can be reduced. The durability of the cleaning brush 1 can be improved.
[0035]
FIG. 4 shows a second embodiment, in which the insertion portion 26 of the cleaning brush 1 is formed of an elastic pipe-shaped resin material. According to the present embodiment, the pair of rollers 19 for moving the cleaning brush 1 forward and backward is formed of a rubber material. However, since the portion in contact with the roller 19 is a resin material, the wear of the roller 19 can be reduced, and Problems caused by generation of shavings and the like can be solved.
[0036]
In this embodiment, the insertion portion 26 of the cleaning brush 1 is formed of an elastic pipe-shaped resin material. However, the outer peripheral surface of the close-wound coil 2a shown in the first embodiment is covered with the resin material. Is also good.
[0037]
According to each of the embodiments, the following configuration is obtained.
[0038]
(Supplementary Note 1) In a cleaning brush for cleaning an endoscope channel, a brush member is provided by twisting brush hair with a hard wire at a distal end portion of a long insertion portion, and an elastic member is further provided at a distal end side of the brush member.
